If your favorite jean jacket were to collab with a peacoat, the result might look something like this. Cut from rigid cotton denim, this jacket has wide lapels, a double-breasted closure, and a hem that hits low on the hip. The fit is relaxed, and a little bit A-line. And it’s finished with slant pockets, strap cuffs, and black suede trim at the collar to match the buttons.

• Main: 100% cotton; trim: 100% suede
